      Oferta manual da Roleta da Sorte pra reserva atual. Normalmente a roleta é enviada
      AUTOMATICAMENTE quando o pagamento do Pix é confirmado. Use este tool só se precisar
      forçar a oferta fora do fluxo normal (reserva já paga que nunca recebeu link).
      Idempotente: chamar 2x na mesma reserva retorna o mesmo link.
